ABSTRACT:
In a variable-transmission-ratio mechanical drive of the continuous variation type having a V-belt and expansible sheaves, in which each sheave has a fixed half-sheave and a movable half-sheave the position of only one of the movable sheaves is determined as a function of the speed and the load of the engine by an automatic positioning servomechanism, whereas the other movable half-sheave is subjected only to the axial load of a member which is adapted to cause the belt to adhere to said expansible sheaves.
